Manifold Pressure Lines, Cabin Frame Joint

An order from Aircraft Spruce showed up today with some 1/4″ ID tygon tubing.  I cut a short piece to connect one outlet of the pressure transducer manifold port to the Dynon manifold pressure sensor.

I used the remaining tubing to connect to the other outlet and ran this through the firewall passthrough.  Inside the fuselage, I’ll transition from 1/4″ ID tubing to 1/8″ ID tubing for the connection to the Lightspeed electronic ignition.

Finally, I fabricated the splice plates for the cabin frame halves.  The pieces that Vans provided for this were not square.  The two short edges were not perpendicular to the long edges.  I laid the holes out square though since the rivets will be seen on the outside of the cabin frame.
